Asthma is the restriction of breathing caused by the swelling of the bronchial tubes through which air is inhaled in the lungs and carbon dioxide exhaled. The swelling is due to a toxic bloodstream and is exacerbated by emotional stress in the same way as other disease conditions are exacerbated when extra fatty acids enter the bloodstream. Irritation by airborne particles such as pollen may also exacerbate the condition but, like stress, is not the primary cause of the disease.
Asthma quickly clears once a very low-fat diet is adopted and the blood freed of lipotoxemia, and asthma is no exception to the rule--applicable to all diseases--that physical exercise is of similar benefit. Although less effective than diet, the effect of regular sustained exercise is to free the blood of fats and lower the blood viscosity. A typical example of the benefits of exercise is the report in the Australian Woman's Day on 31 December 1991. The article headed "I took the plunge and beat Asthma" described how a lady, thin and weak with asthma at age forty-five took up swimming on her doctor's advice and is now, at the age of fifty-nine, happy and healthy although still not completely free of asthma. She could be, if she dieted properly (see Chapter 17: The Proof of the Pudding).
